<title>E2fsprogs: Multiple buffer overflows</title>
|

|
|
<synopsis>
|
||
|
|

||
|
|
execution of arbitrary code.

E2fsprogs provides utilities for use with the ext2 and ext3 file
|
||
|
|
systems including the libext2fs library that allows user-level programs
|
||
|
|
to manipulate an ext2 or ext3 file system.

Rafal Wojtczuk (McAfee AVERT Research) discovered multiple integer
|
||
|
|
overflows in libext2fs, that are triggered when processing information
|
||
|
|
from within the file system, resulting in heap-based buffer overflows.
|
||
|

<impact type="normal">
|
||
|
|
<p>
|
||
|
|
An attacker could entice a user to process a specially-crafted ext2 or
|
||
|
|
ext3 file system image (with tools linking against libext2fs, e.g.
|
||
|
|
fsck, forensic tools or Xen's pygrub), possibly resulting in the
|
||
|
|
execution of arbitrary code with the privileges of the user running the
|
||
|
|
application.
|
||
|
|

|
||
|

</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.

All E2fsprogs users should upgrade to the latest version:
